Which of the following can be a component of an end effector in KUKA robotics?

The option indicating fastening tools like grippers is correct because end effectors in KUKA robotics are designed to interact with the environment and perform specific tasks. Grippers are a primary example of end effectors as they enable the robotic arm to hold, manipulate, and assemble objects. They come in various designs tailored for the intended application, including mechanical fingers, vacuum-based systems, and specialty tools for precise tasks.

Other components such as computational units and battery storage systems generally support the operations of the robot but do not form part of the end effector itself. End effectors focus on the interaction mechanism that directly engages with objects. Operating manuals also do not qualify as a component of an end effector; rather, they serve as guidance documentation for users on how to operate and maintain the robot.
